Crandall Office Furniture’s Herman Miller Mirra aftermarket stool gas cylinders have been constructed to meet original OEM chair specifications and are built to last.
A office chair gas cylinder is the height adjustment mechanism on the chair. The typical life span of a office chair gas cylinder is 4-7 years, depending on use and abuse. If failed, your chair will be left with limited or no height adjustment, however you can quickly and easily replace your broken Herman Miller Mirra stool gas cylinder today.
Our Herman Miller Mirra gas cylinders are made to fit all Herman Miller Mirra chairs.
This cylinder can successfully be used on a standard Herman Miller Mirra chair, to convert it to stool height, standing desk, sit-to-stand desk, or bar height. Also available is our full stool conversion kit (including foot ring) for the Herman Miller Mirra chair.
